Ateleia is a genus of flowering legumes in the family Fabaceae (order Fabales), native to the Neotropics. The genus encompasses roughly 20–30 accepted species of trees and shrubs distributed across Mesoamerica, the Caribbean islands, and South America, with the greatest diversity recorded in Mexico, Cuba, Brazil, and the Central American republics.
The genus was first described by Augustin Pyramus de Candolle and later formally placed by D. Dietrich, with publication cited in Syn. Plant. 4: 1219 (1847); an earlier Bentham treatment appeared in Commentationes de Leguminosarum Generibus (1837). The type species is Ateleia pterocarpa D.Dietr. As members of Fabaceae, species of Ateleia produce characteristic legume fruits and, like many members of the subfamily Papilionoideae, are woody plants of tropical and subtropical forests.
Notable members include Ateleia glazioveana Baill. (native to Brazil and Argentina), Ateleia gummifera (Bertero ex DC.) D.Dietr. (recorded from the Caribbean), Ateleia herbert-smithii Pittier (Mesoamerica), and Ateleia salicifolia Mohlenbr. The genus is rarely cultivated outside specialist botanical collections and remains relatively little studied compared to larger legume genera.
Etymology
The name Ateleia derives from the Greek ateleia (ἀτέλεια), meaning "incompleteness" or "imperfection," a reference to the flowers of the type species, which lack one or more petals compared to a typical papilionoid corolla — an unusual feature within Fabaceae.
Distribution
Ateleia is distributed throughout the Neotropics. GBIF occurrence data places the highest concentrations in Mexico, Brazil, Cuba, Costa Rica, the Dominican Republic, and the Bahamas, with additional records across Central America (El Salvador, Nicaragua, Belize, Honduras, Guatemala), the wider Caribbean, and South America (Colombia, Bolivia, Argentina, Paraguay).
Taxonomy Notes
The genus was established based on Ateleia pterocarpa D.Dietr. as the type species. Authorship is cited as (DC.) D.Dietr. in GBIF, referring to a Candollean basionym brought into combination by Dietrich; an alternative treatment attributes the genus to (DC.) Benth. (1837). The genus belongs to family Fabaceae, order Fabales; its subfamilial placement is within Papilionoideae.
